Chiropractic Kinesiology (CK) is the science and art of utilizing muscle response testing to aid in the evaluation of neurologic/muscular imbalances and in the assessment of proper treatment for correction of the identified imbalances.
Neurologically the human body is divided into compartments: front/back, top/bottom, left/right sides. The brain is responsible for balancing the tone in the muscles between each of these compartments. This is what allows us to stand, bend, run, etc. Proper tone also allows for proper dispersal of stress around joints to maximize lifting potential but more importantly to decrease chance of injuring the joint itself.
